BACKGROUND OF THE PRESENT INVENTION Field of Invention

The present invention relates to a camera module, and more particularlyto an array imaging module and its molded photosensitive assembly andmanufacturing method thereof for electronic device.

Description of Related Arts

Nowadays, most of the electronic products incorporate with an integratedcircuit board to provide multiple functions in one single electroniccomponent. In particular, it is noted that this integratedmulti-function crossovers between trends. For example, the circuit boardconfiguration of the mobile phone which is originally designed forcommunication purpose has been developed into a mobile electronic devicesuch as smart phone that integrally incorporates with the integratedcircuit to provide multiple functions of communication, image capturing,Internet-enabled access, navigation, and other functions. Therefore, theintegrated circuit board must provide all-in-one multifunction for thesmartphone.

Accordingly, most camera modules in the current mobile electronicdevices are single-lens modules. However, this single-lens camera modulecannot meet the requirements of high image quality and capturingeffectiveness in order to meet the requirement of multi-functionalapplication of the current mobile electronic devices.

An advanced camera module, such as a dual lens camera module, has beenalready used in the current mobile electronic device, wherein the duallens camera module is configured to simulate the human eye structure forimage capturing. In particular, the features and performances of thedual lens camera module, such as 3D capturing and scanning ability,gesture and location recognition, color fidelity (color accuracy orcolor balance), rapid focusing ability, panoramic shooting, backgroundfield of depth, and other aspects, are better than the features andperformances of the single lens camera module. Therefore, there is animportant development direction to include more than one lens cameramodule in the future camera industry. Accordingly, the dual lens cameramodule generally comprises two imaging modules, such that during the twoimaging capturing process of the dual lens camera module, two images arecaptured by the imaging modules respectively. Due to the positiondifference between the two imaging modules, the two images will have aspatial position difference. Then, the two images will be processed viaan imaging synthesis method to form a final captured image. It isimportant that the imaging modules must have the uniformity of imagingeffects, such as resolution, shading, color, and the deviation inhorizontal, vertical, and longitudinal directions, wherein theseindications are the major factors to determine the image quality of thedual lens camera module.

However, the current manufacturing and assembling technologies, and thestructure of the dual lens camera module cannot guarantee the imagingquality thereof. As shown in FIG. 1, the existing dual lens cameramodule comprises a circuit board 10P, two lens bases 20P, two imagingmodules 30P, and one supporting frame 40P, wherein a lens motor assembly31P is operatively connected to each of the imaging modules 30P.Accordingly, each of the lens bases 20P is discretely mounted on thecircuit board 10P at one side thereof in order to connect the lens bases20P with each other via the circuit board 10P. The lens motor assembly31P is coupled at and supported by the corresponding lens base 20P. Eachof the lens motor assemblies 31P is enveloped by the supporting frame40P. As shown in FIG. 1B, the two lens bases 20P can be integrated witheach other to form a single base of the dual lens camera moduleaccording to the existing technology. In other words, the lens motorassemblies 31P are mounted at different positions of the lens base 20P.It is appreciated that, through the existing assembling process of theexisting dual lens camera module, each of the lens bases 20P isindividually coupled at the circuit board 10P, such that the dimension,position, etc. . . . of each of the lens bases 20P is hard to control.In other words, the parameters, such as dimension and assemblingposition, of the dual lens camera modules are inconstant. According tothe existing dual lens camera module, as shown in FIG. 1A, the lensbases 20P are individual components and are electrically coupled to thecircuit board 10P in order to connect the lens bases 20P with eachother. Accordingly, the circuit board 10P is a PCB circuit board,wherein the rigidity of the circuit board 10P is relatively weak, suchthat the circuit board 10P is easy to be deformed or bent. As a result,the overall rigidity of the dual lens camera module is hard to controland ensure. After the dual lens camera module is assembled, there willbe a deviation between the two imaging modules 30P during the operationof the dual lens camera module. For example, the distance between thelens motor assemblies 31P cannot be ensured, the positioning toleranceof the lens motor assemblies 31P is relatively large, and the opticalaxis of each of the imaging modules 30P is easily deviated from itsoriginal preset position. Any one of these situations will affect theimage quality of the dual lens camera module. For example, theuncontrollable factors and adverse effects will affect the imagingsynthesis process to form the final captured image. In addition, sincethe lens motor assemblies 31P are wrapped within the supporting frame40P, it is necessary to apply adhesive to a gap between the lens motorassembly 31P and the supporting frame 40P. As a result, the overall sizeof the dual lens camera module will further be relatively increased.

Furthermore, the assembly of the dual lens camera module is based on theconventional COB (Chip On Board) assembling process. The circuit board10P generally comprises a circuit protrusion 11P and a photosensitivechip 12P electrically coupled on the circuit board 10P via a connectingwire such as gold wire 121P. Accordingly, the gold wire 121P has anarc-shape protruded from the board body of the circuit board, such thatthe circuit protrusion 11P and the gold wire 121P protruded from thecircuit board 10P will adversely affect the assembling process of thedual lens camera module.

Since the circuit protrusion 11P and the gold wire 121P are protrudedand exposed from the circuit board 10P, the assembling process will beunavoidably affect by these exposing components. For example, theadhering process of the lens base 20P and the welding process of thelens motor assembly 31P will be affected by the circuit protrusion 11Pand the gold wire 121P. Accordingly, welding resisting agent and dustmay be adhered to the lens base 20P during the welding process of thelens motor assembly 31P. Since the circuit protrusion 11P and thephotosensitive chip 12P are positioned to create a gap therebetween, thedust will be accumulated at the gap thereof. It will contaminate thephotosensitive chip 12P, such that the photosensitive chip 12P willproduce an undesirable result, such as black spots, to affect the imagequality.

Furthermore, the lens base 20P is located at an exterior side of thecircuit protrusion 11P. When the lens base 20P is mounted on the circuitboard 10P, a safety clearance must be provided between the lens base 20Pand the circuit protrusion 11P. In particular, the safety clearanceincludes a horizontal direction and the upward direction of the lensbase 20P with respect to the circuit board 10P. As a result, thethickness of the dual lens camera module will be substantiallyincreased. In other words, it is almost impossible to reduce the overallthickness of the dual lens camera module.

Also, comparing the molding of the dual lens camera module with themolding of the single lens camera module, the coordination of the duallens camera is higher than that of the single lens camera module. Forexample, the optical axes of the imaging modules are required beingcoincident and the optical axes of the lens through the conventional COBprocess must be consistent. Collectively, the overall size of the duallens camera is relatively large, the rigidity of the circuit board isrelatively weak, the flatness of the circuit board is relativelysensitive, and the thickness of the circuit board is relatively large.

Referring to FIGS. 2 to 6A, an array imaging module according to a firstembodiment of the present invention is illustrated, wherein the arrayimaging module comprises a molded photosensitive assembly 20 used toassemble and produce the array imaging module. The molded photosensitiveassembly 20 comprises a mold sealer 27 (also named as molded base inother embodiments) and a photosensitive device 28 which is integrallysealed by and coupled to the mold sealer 27. For example, the moldsealer 27 is molded and formed at the photosensitive device 28.

The photosensitive device 28 comprises a circuit board 22 and at leasttwo photosensitive units 21 which are electrically coupled at thecircuit board 22. In one embodiment, the photosensitive units 21 aremolded and connected to the circuit board 22. In particular, the moldsealer 27 is molded and formed at the photosensitive device 28 byMolding on Chip (MOC) method.

The mold sealer 27 has two optical windows 231, wherein the mold sealer27 is formed at an outer periphery of the photosensitive unit 21. Twooptical lenses 10 are located along optical paths of the photosensitiveunits 21 respectively. In particular, the optical lenses 10 aresupported at the optical windows 231 of the mold sealer 27 correspondingto the locations of the circuit board 22.

The mold sealer 27 comprises a connecting body 271 and two outer annularbodies 272, wherein the connecting body 271 is integrally extendedbetween the outer annular bodies 272, such that the optical windows 231are defined at the outer annular bodies 272 respectively. Accordingly,the photosensitive units 21 are positioned at two sides of theconnecting body 271 respectively. It is worth mentioning that theconnecting body 271 serves as a common sharing portion for the opticallenses 10, such that when the optical lenses 10 are coupled at theconnecting body 271, same portions of the optical lenses 10 will occupythe connecting body 271.

According to the preferred embodiment, the photosensitive device 28comprises a connecting circuit (not shown in drawings) and at least anelectronic element 26. The connecting circuit is pre-formed on thecircuit board 22. The electronic element 26 is electrically connected tothe connecting circuit to couple at the circuit board 22, wherein theelectronic element 26 is electrically connected to the photosensitiveunits 21 for operating the photosensitive process of the photosensitiveunits 21. The electronic element 26 is outwardly protruded from thecircuit board 22. The electronic element 26 can be, but not limit to, aresistor, a capacitor, a diode, a triode, a potentiometer, a relay, aprocessor, a driver, or etc.

It is worth mentioning that the electronic element 26 is enclosed by themold sealer 27 to prevent the exposure of the electronic element 26 fromair outside. In other words, the electronic element 26 is hidden withinthe mold sealer 27 to prevent any contamination, such as dust, from thesurroundings during the operation of the array imaging module. Unlikethe conventional camera module, the electronic element 26, such as thecapacitor, is exposed to the surroundings. Therefore, the mold sealer 27of the present invention can prevent any dust or residue remaining atthe surface of the electronic element 26 to contaminate thephotosensitive unit 21 which may cause a black spot and the like on theimage.

It is worth mentioning that the electronic element 26 is protruded fromthe circuit board 22 in one embodiment. In another embodiment, theelectronic element 26 is embedded in the circuit board 22, such that theelectronic element 26 is not protruded from the circuit board 22. It isappreciated that the structure, type, and location of the electronicelement 26 should not be restricted. Accordingly, the electronic element26 can be enclosed by the connecting body 271 at a position between thetwo photosensitive units 21. Therefore, unlike the conventional cameramodule, the array imaging module of the present invention does notrequire any additional installing space for the electronic element 26 soas to reduce the overall size of the array imaging module.

According to the preferred embodiment, the photosensitive device 28further comprises a plurality of connecting elements such as lead wires24 for electrically connecting to the photosensitive units 21 and thecircuit board 22. In particular, the lead wire 24 can be, but not limitto, gold wire, aluminum wire, copper wire, or silver wire. In addition,the lead wire 24 has a curved configuration to electrically connectbetween the photosensitive units 21 and the circuit board 22.

It is worth mentioning that each of the lead wires 24 is sealed andembedded in the mold sealer 27, wherein the lead wires 24 are enclosedby the mold sealer 27, so as to prevent the exposure of the lead wires24 to outside. When assembling the array imaging module, the lead wires24 will not be damaged by any external contact or any external factor,such as temperature. Therefore, the lead wires 24 can effectively andstably transmit signal between the photosensitive units 21 and thecircuit board 22. The embedded lead wires 24 of the present inventionare superior than the exposed wires of the conventional camera module.

In one embodiment, the optical window 231 of the mold sealer 27 can beconfigured to have a tapered size that a cross section of the opticalwindow 231 is gradually increased from bottom to top.

It is worth mentioning that the electronic element 26 and the lead wires24 are enclosed by the mold sealer 27, such that the electronic element26 and the lead wires 24 are protected by the mold sealer 27. It isappreciated that the mold sealer 27 can be directly molded and formed atthe circuit board 22 while the one or more electronic elements 26 areembedded in the circuit board 22. In addition, the mold sealer 27 canalso formed at different locations of the electronic elements 26, suchas at an outer periphery of the electronic elements 26 or surroundingthe electronic elements 26.

Furthermore, each of the photosensitive unit 21 has a photosensitivearea 212 and a non-photosensitive area 213, wherein the photosensitivearea 212 is encircled within the non-photosensitive area 212 and isarranged for providing photosensitive effect. The lead wires 24 areoperatively linked to the non-photosensitive area 213.

According to the preferred embodiment, the mold sealer 27 is extended tothe non-photosensitive area 213 of the photosensitive unit 21 and isoverlappedly coupled at the circuit board 22 via the molding process.Through the molding process, such as Molding on Chip (MOC) method, themold sealer 27 can be enlarged its covering area at its inwarddirection, so as to reduce the outward extension of the mold sealer 27.As a result, the size of the mold sealer 27 can be reduced to minimizethe length and width size of the array imaging module.

According to the preferred embodiment, the mold sealer 27 is protrudedlyencircled around an outer periphery of the photosensitive area 212 ofthe photosensitive unit 21. In particular, the mold sealer 27 isintegrally connected to the photosensitive unit 21 to provide a goodsealing effect therefor. In other words, when the molded photosensitiveassembly 20 is assembled, the photosensitive device is sealed andenclosed therewithin to form a closed environment.

Referring to FIGS. 4 and 5, during the manufacturing process of themolded photosensitive assembly 20, the circuit board 22, which can be aconventional circuit board, can be used for supporting the twophotosensitive units 21, such as coupling the two photosensitive units21 on the circuit board 22. Then, the two photosensitive units 21 can beelectrically connected to the circuit board 22 via the lead wires 24,such as gold wire connection. Then, the photosensitive units 21 and thecircuit board 22 can be initially packed and sealed by molding processto form an integral body. For example, by using a mold injection machinefor introducing or injecting mold material via Insert Molding technologyand Surface Mount Technology to mold and form the mold sealer 27 or viaa semiconductor packaging technology and press mold technology to moldand form the mold sealer 27. The circuit board 22 can be, but notlimited to, a soft-hard combination board, ceramic substrate(non-flexible board), or a hard PCB board (non-flexible board). Themolding process can be, but not limit to, the injection molding processor press-molding process. The injection mold material can be nylon, LCP(Liquid Crystal Polymer), PP (Polypropylene), or the like. It isappreciated that different materials can be selectively used indifferent molding processes and should not be restricted in the presentinvention. The process of forming the mold sealer 27 should not berestricted in the present invention.

Furthermore, the mold sealer 27 has an enclosing portion 273 and a lightfilter mounting portion 274 integrally extended from the enclosingportion 273. The enclosing portion 273 is molded and coupled at thecircuit board 22 to enclose the one or more electronic elements 26 andthe lead wires 24. The light filter mounting portion 274 is arranged forcoupling with a light filter 40. In other words, when assembling themolded photosensitive assembly 20 of the array imaging module, the lightfilter 40 can be coupled at the light filter mounting portion 274 toensure the light filter 40 to be aligned along the photosensitive pathof the respective photosensitive unit 21 without any additional lightfilter supporting frame. Therefore, the mold sealer 27 also serves as asupporter to support the light filter 40. Due to the molding process,the size and shape of the mold sealer 27 can be modified to have aflatness, such that the light filter 40 can be stably coupled at thelight filter mounting portion 274, wherein this feature cannot beachieved by the conventional camera module.

In addition, the light filter mounting portion 274 has two couplingslots 2741 formed corresponding to the optical windows 231 for engagingwith the photosensitive units 21 respectively. Therefore, the lightfilter mounting portion 274 provides enough space for the light filter40 to prevent the light filter 40 being protruded from a top side of thelight filter mounting portion 274. In other words, the two couplingslots 2741 are formed at the light filter mounting portion 274 that thelight filters 40 are engaged with the coupling slots 2741 withoutprotruding out of the top side of the light filter mounting portion 274.Accordingly, the light filter 40 can be an infrared cut-off lightfilter, IRCF.

It is worth mentioning that the coupling slots 2741 can be engaged withthe light filters 40 respectively in one embodiment. In anotherembodiment, the coupling slots 2741 can be used for engaging with motorsor lens barrels of the array imaging module respectively. It isappreciated that the size and shape of the coupling slot 2741 should notbe restricted in the present invention.

It is worth mentioning that the inner wall of the mold sealer 27 can beconfigured corresponding to the shape of the lead wire 24. For example,the inner wall of the mold sealer 27 can be configured in a slantedmanner to not only enclose the lead wire 24 but also reduce anyreflected stray light from the inner wall of the mold sealer 27 so as toenhance the imaging quality of the array imaging module. It isappreciated that the shape of the mold sealer 27 should not berestricted in the present invention.

In particular, the first connecting wire 291 iselectrically connected to the circuit board 22. In other words, thefirst connecting wire 291 is electrically connected to the connectingcircuit of the circuit board 22. Accordingly, the first connecting wire291 is enclosed in the mold sealer 27 and extended to the top side ofthe mold sealer 27. The first connecting wire 291 has a motor connectingend 2911 extended above and exposed from the top side of the mold sealer27 to electrically connect to the driver connecting terminal 31 of thedriver 30. It is worth mentioning that the first connecting wire 291 canbe embedded in the mold sealer 27 during the mold sealer 27 is formed.In view of the conventional camera module, the driver must beelectrically connected to the circuit board via a separated wire bywelding two ends of the wire at the driver and the circuit board, suchthat the manufacturing process of the conventional camera module iscomplicated. In the preferred embodiment, the first connecting wire 291is pre-formed in the mold sealer 27 to replace the conventional weldingprocess of the separated wire. Therefore, the driver connecting terminal31 can be electrically connected to the motor connecting end 2911 of thefirst connecting wire 291 via an anisotropic conductive film or welding.

It is worth mentioning that the embedded location of the firstconnecting wire 291 and the exposing location of the motor connectingend 2911 can be modified according to the requirement of the driver 30.For example, the motor connecting end 2911 of the first connecting wire291 is located at an outer peripheral portion of the mold sealer 27,i.e. the top side of the mold sealer 27 in one embodiment. In anotherembodiment, the motor connecting end 2911 of the first connecting wire291 is located at an inner peripheral portion of the mold sealer 27,i.e. the bottom side of the coupling slot 2741. Therefore, differentlocations of the first connecting wire 291 are designed for connectingdifferent drivers 30. In other words, when the driver 30 is required forinstalling at the top side of the mold sealer 27, the motor connectingend 2911 of the first connecting wire 291 is extended to the outerperipheral portion of the mold sealer 27 at the top side thereof. Whenthe driver 30 is required for installing at the coupling slot 2741, themotor connecting end 2911 of the first connecting wire 291 is extendedto the inner peripheral portion of the mold sealer 27 at the bottom sideof the coupling slot 2741.

In other words, during the manufacturing process of the moldedphotosensitive assembly 20, the photosensitive unit 21 is initiallymounted on and electrically connected to the circuit board 22, and thenthe mold sealer 27 is molded on the circuit board 22 via the MOC(Molding on Chip) method. During the molding process, the firstconnecting wire 291 is pre-formed and embedded in the mold sealer 27 toensure the first connecting wire 291 to be electrically connected to thecircuit board 22. At the same time, the motor connecting end 2911 of thefirst connecting wire 291 is exposed out of the top side of the moldsealer 27 for electrically connecting to the driver connecting terminal31 of the driver 30. For example, when the molded photosensitiveassembly 20 is in use for the array imaging module, the driverconnecting terminal 31 of the driver 30 can be connected to the motorconnecting end 2911 of the first connecting wire 291 by welding.Therefore, the driver 30 is electrically connected to the circuit board22 without any additional separated wire, so as to reduce the length ofthe driver connecting terminal 31 of the driver 30.

Referring to FIGS. 2 to 6A, the array imaging module can be an AutomaticFocus Camera Module (AFCM). The array imaging module is constructed tohave the molded photosensitive assembly 20, two light filters 40, twodrivers 30, and two optical lenses 10.

The light filters 40 are installed at the molded photosensitive assembly20, wherein the optical lenses 10 are installed to the drivers 30respectively, and the drivers 30 are installed at the moldedphotosensitive assembly 20.

In addition, the light filters 40 are coupled at the coupling slots 2741of the light filter mounting portion 274 of the mold sealer 27. Thedrivers 30 are coupled at the top side of the light filter mountingportion 274 of the mold sealer 27 of the molded photosensitive assembly20.

The second connecting wire 293 has a second motorconnecting end 2931 extended to the bottom wall of the first terminalslot 292 for electrically connecting to the driver connecting terminal31 of the driver 30. In particular, the second motor connecting end 2931can be formed as a connecting pad. The second connecting wire 293 can bea conductive wire embedded in the mold sealer 27. Therefore, the driverconnecting terminal 31 of the driver 30 can be easily connected to thefirst terminal slot 292. For example, when the molded photosensitiveassembly 20 is in use for the array imaging module, the driverconnecting terminal 31 of the driver 30 can be inserted into the firstterminal slot 292 and connected to the second motor connecting end 2931of the second connecting wire 293 by welding. Therefore, the driver 30is electrically connected to the circuit board 22 without any additionalseparated wire. The driver 30 can be stably connected to prevent anyexternal force or contact to the driver connecting terminal 31 of thedriver 30. In particular, the second motor connecting end 2931 of thesecond connecting wire 293 can be a welding pad. The second connectingwire 293 can be a conductive wire embedded in the mold sealer 27.

During the molding process, the first terminal slot 292 with apredetermined length is pre-formed in the mold sealer 27. At the sametime, the second connecting wire 293 is electrically connected to thecircuit board 22, wherein the second motor connecting end 2931 ispre-set to extend to the bottom wall of the first terminal slot 292.Accordingly, the second connecting wire 293 can be a conductive wireembedded in the mold sealer 27.

The motor connecting unit 29 comprises asecond terminal slot 294 for receiving the driver connecting terminal 31of the driver 30. The second terminal slot 294 is embedded in the moldsealer 27. The motor connecting unit 29 further comprises a circuitterminal 295 which is pre-set on the circuit board 22 and iselectrically connected to the connecting circuit of the circuit board22. In addition, the second terminal slot 294 is extended from the topside of the mold sealer 27 to the circuit board 22 toward the circuitterminal 295. Therefore, in one embodiment, when the driver connectingterminal 31 of the driver 30 is inserted into the second terminal slot294, the driver connecting terminal 31 of the driver 30 is electricallyconnected to the circuit terminal 295 by welding.

In other words, during the manufacturing process of the moldedphotosensitive assembly 20, the photosensitive unit 21 is initiallyformed and electrically connected to the circuit board 22 and thecircuit terminal 295 is pre-formed on the circuit board 22, wherein themold sealer 27 is then formed on the circuit board 22 via the MOCmethod. During the molding process, the second terminal slot 293 with apredetermined length is pre-formed in the mold sealer 27 and extendedtoward the circuit terminal 295. Therefore, the driver connectingterminal 31 of the driver 30 can be easily connected. For example, whenthe molded photosensitive assembly 20 is in use for the array imagingmodule, the driver connecting terminal 31 of the driver 30 can beinserted into the second terminal slot 293 and connected to the circuitterminal 295 by welding. Therefore, the driver 30 is electricallyconnected to the circuit board 22 that the driver 30 can be stablyconnected to prevent any external force or contact to the driverconnecting terminal 31 of the driver 30.

FIG. 7C illustrates another alternative mode of the motor connectingunit of the present invention. The motor connecting unit 29 comprises anengraving circuit 296 electrically connected to the connecting circuitof the circuit board 22, the photosensitive unit 21, and the motor. Forexample, the engraving circuit 296 can be formed by Laser DirectStructuring (LDS) method to embed at the mold sealer 27 at apredetermined position. According to the conventional connecting method,the motor is electrically connected to the circuit board via anindividual wire, such that the manufacturing process thereof isrelatively complicated. In view of the present invention, the engravingcircuit 296 can replace the conventional welding process for electricalconnection, such that the electrical connection of the present inventionwill be more stable comparing with the conventional one. In particular,the engraving circuit 296 is formed by forming an engraving groove atthe mold sealer 2201 and metal-plating the engraving groove.

According to the first embodiment, the driver 30 can be electricallyconnected to the molded photosensitive assembly 20 by the motorconnecting unit 29, such as via the first connecting wire 291.

FIG. 8 illustrates an alternative mode of the array imaging module ofpresent invention. The array imaging module can be a fixed focus cameramodule which comprises a molded photosensitive assembly 20, two lightfilters 40, and two optical lenses 10.

The light filters 40 are installed at the molded photosensitive assembly20, wherein the optical lenses 10 are installed on the moldedphotosensitive assembly 20.

In particular, the light filters 40 are coupled at the coupling slots2741 of the light filter mounting portion 274 of the mold sealer 27respectively. The optical lenses 10 are coupled at the top side of themold sealer 27.

It is worth mentioning that the optical lenses 10 are coupled at the topside of the mold sealer 27 of the molded photosensitive assembly 20,such that the mold sealer 27 also serves as a supporter to support andretain the optical lenses 10 in position. However, the assembly of thearray imaging module is different from the conventional COB process. Theconventional COB process is that the supporting frame is adhered on thecircuit board. In view of the present invention, the mold sealer 27 ismolded and sealed at the circuit board 22, such that no adhering step isinvolved in the present invention to enhance the stability of theconnection and controllability of the process. Since the mold sealer 27is molded on the circuit board 22 to enclose the one or more electronicelements 26, there is no need to reserve any installing clearancebetween the mold sealer 27 and the electronic element 26, such that thethickness of the array imaging module will be reduced. In addition, theelectronic elements 26 and the lead wires 24 are able to be overlappedlyembedded in the mold sealer 27, wherein the electronic elements 26 andthe lead wires 24 can be shared with the common area. Unlike theconventional camera module, the electronic elements and the wires mustkeep a predetermined safety distance with each other. Accordingly, theheight of the mold sealer 27 that also provides the supporting functioncan be reduced. In addition, since the mold sealer 27 can replace theconventional supporting frame, the mold sealer 27 can minimize the tilterror so as to reduce the cumulative tolerance of the array imagingmodule. Moreover, since the lead wires 24 are enclosed by the moldsealer 27 and the mold sealer 27 is extended to the non-photosensitivearea 213 of the photosensitive unit 21, the size of the mold sealer 27can be reduced to further reduce the length and width size of the arrayimaging module.

FIG. 9 illustrates a second preferred embodiment of the array imagingmodule and its photosensitive units of the present invention. Thedifference between this second embodiment and the above embodiment isthat, the circuit board 22H has two inner indentation grooves 2222H,wherein the photosensitive units 21 are received in the innerindentation grooves 2222H to enclose the photosensitive units 21therewithin, so as to reduce the relative height difference between thephotosensitive units 21 and the circuit board 22H. Therefore, when themold sealer 27 is molded to enclose the photosensitive units 21, theheight of the mold sealer 27 will be reduced to minimize the height ofthe array imaging module.

FIG. 10 illustrates a third preferred embodiment of the array imagingmodule and its photosensitive units of the present invention.

The difference between this third preferred embodiment and the aboveembodiments is that, the molded photosensitive assembly 20 furthercomprises a reinforcing layer 2801 overlapped and coupled at the bottomside of the circuit board 22 to enhance the strength of the circuitboard 22. In other words, the reinforcing layer 2801 is overlapped andcoupled at the bottom side of the circuit board 22 at the area where themold sealer 27 and the photosensitive unit 21 are coupled on the topside of the circuit board 22, so as to ensure the strength of thecircuit board 22 to support the mold sealer 27 and the photosensitiveunit 21.

In addition, the reinforcing layer 2801 can be a metal panel coupled atthe bottom side of the circuit board 22 not only to enhance the strengthof the circuit board 22 but also to enhance the heat dissipating powerof the molded photosensitive assembly 20 to effectively dissipate heatgenerated by the photosensitive unit 21.

It is worth mentioning that the circuit board 22 can be a Flex PrintCircuit (FPC). Through the rigidities of the reinforcing layer 2204C andthe circuit board 22, the flex print circuit, having a bendable ability,can fulfill the supportive ability of the molded photosensitive assembly20. Accordingly, the circuit board 22 can be the Print Circuit Board(PCB), the FPC, or Rigid Flex (RF). In other words, the reinforcinglayer 2801 can substantially increase the strength of the circuit board22 and effectively enhance the heat dissipation, so as to reduce thethickness of the circuit board 22. Therefore, the height of the circuitboard assembly will be substantially reduced to minimize the height ofthe array imaging module.

As shown in FIGS. 10B and 10C, the circuit board 22 has at least areceiving chamber 224, wherein the photosensitive unit 21 is received inthe receiving chamber 224 of the circuit board 22 to minimize the heightdifference between the top side of the photosensitive unit 21 and thetop side of the circuit board 22. Preferably, the top side of thephotosensitive unit 21 and the top side of the circuit board 22 arealigned with the same planar direction. Therefore, the height of thearray imaging module can be further reduced. The array imaging modulecan be incorporated with the thinness of the electronic device. It isworth mentioning that the receiving chamber 224 can be a receiving slot,as shown in FIG. 10B. As shown in FIG. 10C, the receiving chamber 224can be a receiving through hole, wherein when the photosensitive units21 are electrically connected to the circuit board 22, thephotosensitive units 21 are disposed in the receiving chamber 224 andthe reinforcing layer 2081 is coupled at the bottom side of the circuitboard 22 to enhance the strength of the circuit board 22.

FIG. 11 illustrates a fourth preferred embodiment of the array imagingmodule and its photosensitive units of the present invention.

The difference between this fourth embodiment and the above embodimentsis that, the circuit board 22 further has at least a reinforcing slot220J, wherein the mold sealer 27 is extended into the reinforcing slot220J to enhance the strength of the circuit board 22.

The position of each of the reinforcing slots 220J can be selectivelymodified according to the rigidity of the circuit board 22. Preferably,the reinforcing slots 221J are symmetrically formed on the circuit board22. Accordingly, the rigidity of the circuit board 22 can be enhanced bythe reinforcing slot 220J to reduce the thickness of the circuit board22, so as to reduce the thickness of the array imaging module and toenhance the heat dissipation of the molded photosensitive assembly 20.

It is worth mentioning that the reinforcing slot 220J is embodied as anindention cavity, wherein the reinforcing slot 227D is not a throughslot, such that when the reinforcing slot 220J is formed on the circuitboard 22, the reinforcing slot 220J will not extended through thecircuit board 22. Therefore, the mold sealer 27 will not be extendedthrough the circuit board 22 and will not be leaked from the reinforcingslot 220J.

As shown in FIG. 12, an array imaging module with its moldedphotosensitive assembly 20 according to a fifth preferred embodiment ofthe present invention is illustrated.

The difference between this fifth preferred embodiment and the aboveembodiments is that, the circuit board 22 has a least a reinforcing slot220K, wherein the mold sealer 27 is extended into the reinforcing slot220K to enhance the strength of the circuit board 22.

The positions of each of the reinforcing slots 220K can be selectivelymodified according to the rigidity of the circuit board 22. Preferably,the reinforcing slots 220K are symmetrically formed on the circuit board22. Accordingly, the rigidity of the circuit board 22 can be enhanced bythe reinforcing slot 220K to reduce the thickness of the circuit board22, so as to reduce the thickness of the array imaging module and toenhance the heat dissipation of the molded photosensitive assembly 20.

It is worth mentioning that the reinforcing slot 220K is a through slot,such that when the reinforcing slot 220K is formed on the circuit board22, the reinforcing slot 220K will extended through the circuit board22. The two opposite sides of the circuit board 22 are communicate witheach other through the reinforcing slot 220K. Therefore, the mold sealer27 will be extended through the circuit board 22 to integrally form withthe circuit board 22 so as to combine the mold sealer 27 with thecircuit board 22 with a composite material structure. In addition, thereinforcing slot 220K as the through slot can be easily formed on thecircuit board 22.

The light filter mounting portion 274L and the lensmounting portion 275L are integrally formed with the enclosing portion273L in a sequent manner during the molding process, such that the lightfilter mounting portion 274L is integrally formed between the enclosingportion 273L and the lens mounting portion 275L. The enclosing portion273L is molded and formed to couple with the circuit board 22 and toenclose the electronic element 26 and the lead wires 24. The lightfilter mounting portion 274L is molded and formed to couple with thelight filter 40. In other words, during the manufacturing process of themolded photosensitive assembly 20 for the array imaging module, thelight filter 40 is mounted and supported at the light filter mountingportion 22014L, such that the light filter 40 is automatically retainedalong the photosensitive path of the photosensitive unit 21 withoutincorporating any conventional supporting frame. Therefore, the lightfilter mounting portion 274L has a supportive ability. Due to themolding process, the top side of the light filter mounting portion 274Lcan be made to have a flat surface to evenly support the light filter40, which is superior than the conventional camera module. The lensmounting portion 275L is coupled to the optical lens 10. In other words,during the manufacturing process of the molded photosensitive assembly20 for the array imaging module, the optical lens 10 can be mounted andsupported at the inner side of the lens mounting portion 275L, so as tostably retain the optical lens 10 in position.

The mold sealer 27L comprises a connecting body 271L and two outer ringbodies 272L, wherein the connecting body 271L is mold-connected betweenthe two outer ring bodies 272L to spacedly separate the outer ringbodies 272L by the connecting body 271L. Accordingly, each of the outerring bodies 272L forms the corresponding optical window 231L. The twophotosensitive units 21 are positioned at two lateral sides of theconnecting body 271L to form the array imaging module. It is worthmentioning that the connecting body 271L serves as a common body orsharing body that when installing the optical lenses 10, the opticallenses 10 will take even portions of the connecting body 271L.

Furthermore, the light filtering portion 274L has two mounting grooves2741L are spacedly formed at the light filtering portion 274L, whereinthe two mounting grooves 2741L are located corresponding to the opticalwindow 231L. The mounting grooves 2741L provide a mounting space,wherein a peripheral edge of the light filter 40 is engaged with themounting grooves 2741L, such that the light filter 40 can be stablymounted at the mold sealer 27L.

In other words, the light filter mounting portion 274L and the lensmounting portion 275L are extended integrally and upwardly to form astep-like platform at the inner sides thereof to stably support thelight filter 40 and the optical lens 10 without any addition supportingframe to support thereof.

The lens mounting portion 275L further has two lens inner walls 2752L,wherein each of the lens inner walls 2752L has a closed annular shape,such that a lens edge gap is formed between the lens inner walls 2752L.It is worth mentioning that each of the lens inner walls 2752L is a flatsurface to couple with the optical lens 10 without any threadedstructure, so as to form the fixed focus lens module. It is worthmentioning that the optical lens 10 can be coupled at the lens mountingportion 275L by adhesive.

As shown in FIGS. 15 and 16, an array imaging module and photosensitiveunits according to an eighth embodiment of the present invention isillustrated, wherein the array imaging module comprises a moldedphotosensitive assembly 20N, wherein the optical lens 10 is installed ontop of the molded photosensitive assembly 20 to form the array imagingmodule.

In particular, the optical lens 10 is adhered to affix on the top sideof the mold sealer 27N of the molded photosensitive assembly 20. Takingadvantage of the molding technology, the top side of the molded sealer27N provides a flat surface for stably supporting the optical lens 10thereon for enhancing the imaging quality of the array imaging module.The molded photosensitive assembly 20N is used to assemble tomanufacture the array imaging module for making the molded cameramodule.

The molded photosensitive assembly 20N comprises the mold sealer 27N andthe photosensitive device 28N, wherein the mold sealer 27N is molded andintegrally formed with the photosensitive device 28N.

The photosensitive device 28N comprises a circuit board 27N. The moldsealer 27N has two optical windows 231N, wherein the mold sealer 27N isformed at an outer periphery of the photosensitive unit 21N. Two opticallenses 10 are located along optical paths of the photosensitive units21N respectively. In particular, the optical lenses 10 are supported atthe optical windows 231N of the mold sealer 27N corresponding to thelocations of the circuit board 22N.

The mold sealer 27N comprises a connecting body 271N and two outerannular bodies 272N, wherein the connecting body 271N is integrallyextended between the outer annular bodies 272N to separate outer annularbodies 272N into two adjacent portions, such that the optical windows231N are defined at the outer annular bodies 272N respectively, whereinthe two photosensitive units 21N are positioned at two sides of theconnecting body 271N respectively so as to enable the assembling of thearray imaging module. It is worth mentioning that the connecting body271N serves as a common sharing portion for the drivers 30, such thatwhen the drivers 30 are coupled at the connecting body 271N of the moldsealer 27N, at least a portion of each of the drivers 30 will beassembled at different position of the connecting body 271N.

The photosensitive device 28N comprises a circuit board 22N and at leasttwo photosensitive units 21N which are electrically coupled at thecircuit board 22N. According to the preferred embodiment, thephotosensitive units 21N are molded to connect with the circuit board22N.

According to the preferred embodiment, the photosensitive device 28Ncomprises a connecting circuit (not shown in the drawings) and at leastan electronic element 26N. The connecting circuit is pre-formed on thecircuit board 22N. The electronic element 26N is electrically connectedto the connecting circuit to couple at the circuit board 22N, whereinthe electronic element 26N is electrically connected to thephotosensitive units 21N for operating the photosensitive process of thephotosensitive units 21N. The electronic element 26N is outwardlyprotruded from the circuit board 22N. The electronic element 26N can be,but not limit to, a resistor, a capacitor, a diode, a triode, apotentiometer, a relay, a processor, or a driver.

It is worth mentioning that the electronic element 26N is enclosed bythe mold sealer 27N to prevent the exposure of the electronic element 26to outside. In other words, the electronic element 26N is hidden withinthe mold sealer 27N to prevent any contamination, such as dust, from thesurroundings during the operation of the array imaging module. Unlikethe conventional camera module, the electronic element 26N, such as thecapacitor, are exposed to the surroundings. Therefore, the mold sealer27N of the present invention can prevent any dust or residue remainingat the surface of the electronic element 26N to contaminate thephotosensitive unit 21N which may cause adverse effect such as blackspot and the like on the image.

According to the preferred embodiment, the photosensitive device 28Nfurther comprises a plurality of lead wires 24N for electricallyconnecting to the photosensitive units 21N and the circuit board 22N. Inparticular, the lead wire 24N can be, but not limit to, gold wire,aluminum wire, copper wire, or silver wire.

It is worth mentioning that each of the lead wires 24N is embedded inthe mold sealer 27N, wherein the lead wires 24N are enclosed by the moldsealer 27N, so as to prevent the exposure of the lead wires 24N tooutside. When assembling the array imaging module, the lead wires 24Nwill not be damaged by any external contact or any external factor, suchas temperature. Therefore, the lead wires 24N can effectively and stablytransmit signals between the photosensitive units 21N and the circuitboard 22N. The embedded lead wires 24N of the present invention aresuperior than the exposed wires of the conventional camera module.

It is worth mentioning that the electronic element 26N and the leadwires 24N are enclosed by the mold sealer 27N, such that the electronicelement 26N and the lead wires 24N are protected by the mold sealer 27Nfor enabling the camera module to achieve better performance. Personskilled in the art should understand that the mold sealer 27N is notlimited to enclose the electronic element 26N and the lead wires 24N. Inother words, according to other embodiments, the mold sealer 27N can bedirectly molded and formed at the circuit board 22N while the electronicelement 26N is embedded in the circuit board 22N without protruding onthe circuit board 22N. In addition, the mold sealer 27N can also formedat different locations of the electronic element 26N, such as at anouter periphery of the electronic element 26N or surrounding theelectronic element 26N.

Furthermore, the photosensitive unit 21N has a photosensitive area 212Nand a non-photosensitive area 213N, wherein the photosensitive area 212Nis encircled within the non-photosensitive area 212N and is arranged forproviding photosensitive effect. The lead wire 24N is operatively linkedto the non-photosensitive area 213N.

According to the preferred embodiment, the mold sealer 27N is extendedto the non-photosensitive area 213N of the photosensitive unit 21N andis overlappedly coupled at the circuit board 22N via the moldingprocess. Through the molding process, such as Molding on Chip (MOC)method, the covering area of the mold sealer 27N can be enlarged at itsinward direction, so as to reduce the outward extension of the moldsealer 27N. As a result, the length and width of the mold sealer 27N canbe reduced to minimize the size of the array imaging module.

The molded photosensitive assembly 20N further comprises two lightfilters 40N overlappedly coupled above the photosensitive units 21N. Aperiphery of each of the light filters 40N is coupled at the mold sealer27N to retain the light filter 40N in position. It is worth mentioningthe light filters 40N cover on top of the photosensitive units 21Nrespectively to protect and separate the photosensitive units 21N fromoutside so as to prevent any damage of the photosensitive units 21N.

During the manufacturing process of the molded photosensitive assembly20N, the photosensitive units 21N are initially formed at the circuitboard 22N by, for example, attaching on the circuit board 22N, such thatthe photosensitive units 21N are electrically connected to the circuitboard 22N via the lead wires 24N. Then, the light filters 40N arepositioned on top of the photosensitive units 21N.

As shown in FIG. 24, thearray imaging module further comprises at least two drivers 30′, whereinthe drivers 30′ are operatively coupled to the optical lenses 10′respectively. Each of the drivers 30′ is supported and coupled at themolded base 23′ at the top side thereof to retain the optical lenses 10′at the optical paths of the photosensitive units 21′ of the moldedphotosensitive assembly 20′ respectively.

As shown in FIG. 24, the array imaging module further comprises at leasta light filter 40′. In one embodiment, the present invention comprisesat least a lighter filter 40′, wherein the light filter 40′ is coupledat the top side of the molded base 23′, such that the light filter 40′can be located at different positions corresponding to the optical pathof the photosensitive unit 21′. In another embodiment, the array imagingmodule further comprises two or more light filters 40′, wherein thelight filters 40′ are coupled at the top side of the molded base 23′,such that the light filters 40′ can be located corresponding to theoptical paths of the photosensitive units 21′. In other words, thephotosensitive units 21′, the light filters 40′, and the optical lenses10′ are coupled respectively.

During the operation of the array imaging module, the light reflected bythe object is guided to pass through the optical lens 10′ into theinterior of the array imaging module. Then, the light will pass throughthe light filter 40′ to the photosensitive unit 21′, such that thephotosensitive unit 21′ will receive the reflected light along theoptical path for photoelectric conversion. Accordingly, the light filter40′ is arranged for filtering stray light, such as the infrared lightportion, in the light from the optical lens 10′ for improving theimaging quality of the array imaging module.

For example, the infrared cut filter andthe full transmissible spectral filter can form a combination of lightfiltering unit, such that the infrared cut filter and the fulltransmissible spectral filter can be selectively switched to locatealong the optical path of the photosensitive unit 21′. For example, theinfrared cut filter is selectively switched to locate along the opticalpath of the photosensitive unit 21′ when the array imaging module isoperated under the day light environment in which the environmentallight is sufficient. Therefore, the infrared light portion of the lightwill be filtered by the infrared cut filter when entering into theinterior of the array imaging module. Likewise, the full transmissiblespectral filter is selectively switched to locate along the optical pathof the photosensitive unit 21′ when the array imaging module is operatedunder the dark environment in which the environmental light isinsufficient. Therefore, the infrared light portion of the light willnot be filtered by the infrared cut filter when entering into theinterior of the array imaging module.

The molded photosensitive assembly 20′ further comprises at least asupporting member 25′, wherein the supporting member 25′ protects thelead wires 24′ and the photosensitive units 21′ during the moldingprocess. According to the preferred embodiment, at least two supportingmembers 25′ are provided. Preferably, the number of the supportingmember 25′ matches with the number of the photosensitive unit 21′.Before the molded base 23′ is formed, the non-photosensitive areas 213′of the photosensitive units 21′ are covered by the supporting members25′ respectively. After the molded base 23′ is formed, the molded base23′ will cover and enclose the peripheral areas 223′ of the circuitboard 22′, portions of the non-photosensitive areas 213′ of thephotosensitive units 21′, and portions of the supporting members 25′, soas to form the molded photosensitive assembly 20′. The supportingmembers 25′ can enhance the quality of the array imaging module and theimaging quality thereof. In another embodiment, there is only onesupporting member 25′ being used as disclosed later.

Each of the supporting members 25′ comprises an encircling frame shapedsupporting body 251′ and a through hole 252′, wherein the supportingbody 251′ of the supporting member 25′ is coupled on at least a portionof the non-photosensitive area 213′ of the photosensitive unit 21′. Thephotosensitive area 212′ of the photosensitive unit 21′ is aligned withthe through hole 252′ of the supporting member 25′. Preferably, thesupporting body 251′ of the supporting member 25′ is coupled on at leasta portion of each of the chip inner lateral side 2131′, the chipconnecting portion 2132′, and the chip outer lateral side 2133′ of thenon-photosensitive area 213′ of the photosensitive unit 21′. Inaddition, the supporting body 251′ of the supporting member 25′ has atop side 2501′, an inner lateral side 2502′, and an outer lateral side2503′. According to the preferred embodiment, the side of the supportingbody 251′ facing toward the photosensitive area 212′ is defined as theinner lateral side 2502′ of the supporting body 251′. The side of thesupporting body 251′ facing toward the peripheral area 223′ of thecircuit board 22′ is defined as the outer lateral side 2503′ of thesupporting body 251′. In one embodiment, the molded base 23′ is formedto enclose at least a portion of each of the outer lateral side 2503′and the top side 2501′ of the supporting body 251′.

In addition, the molded photosensitive assembly 20′ further comprisesone or more electronic elements 26′ which are treated by Surface MountTechnology (SMT) to electrically couple at the peripheral portion 223′of the circuit board 22′. Preferably, each of the electronic elements26′ is electrically coupled at the peripheral portion 223′ of thecircuit board 22′ at the circuit board outer lateral side 2233′ thereof.Accordingly, the photosensitive unit 21′ and the electronic elements 26′can be coupled at the same side of the circuit board 22′ or two opposedsides of the circuit board 22′. For example, the photosensitive unit 21′and the electronic elements 26′ can be coupled at the same side of thecircuit board 22′ in one embodiment, wherein the photosensitive unit 21′is coupled at the chip coupling areas 222′ of the circuit board 22′ andthe electronic elements 26′ are coupled at the peripheral area 223′ ofthe circuit board 22′. When the molded base 23′ is formed to enclose theperipheral area 223′ of the circuit board 22′, the molded base 23′ willenclose the electronic elements 26′. Therefore, the electronic elements26′ are individually isolated and are separated from the photosensitiveunit 21′. Accordingly, even though the distance between two adjacentelectronic elements 26′ is reduced, the molded base 23′ can prevent themutual interference by the adjacent electronic elements 26′. Since themolded base 23′ encloses all the electronic elements 26′ to prevent theelectronic elements 26′ from exposing and contacting with outside so asto prevent any contaminate the photosensitive area 212′ of thephotosensitive unit 21′. In other words, the size of the array imagingmodule can be further reduced and the imaging quality of the arrayimaging module can be enhanced. Therefore, through the enclosing of theelectronic elements 26′ within the molded base 23′, the area of thecircuit board 22′ can be further reduced and more electronic elements26′ can be electrically coupled at the circuit board 22′ with a limitedinstalling area. The electronic element 26′ can be, but not limit to, aresistor, a capacitor, a diode, a triode, a potentiometer, a relay, aprocessor, or a driver.

It is worth mentioning that the molded base 23′, the photosensitive unit21′, and the circuit board 22′ are combined to form an integratedstructure, the molded base 23′ will serves as a reinforcing portion toreinforce the structure of the circuit board 22′. In other words, themolded base 23′ will enhance the strength of the circuit board 22′ afterthe circuit board 22′ is coupled with the molded base 23′. Even though athinner circuit board 22′ is used, the circuit board 22′ will not beeasily deformed when the strength of the circuit board 22′ is enhancedby the molded base 23′. Therefore, the imaging quality of the arrayimaging module can be enhanced.

When the photosensitive unit 21′ is coupled at and is electricallyconnected with the circuit board 22′, the molded base 23′ is molded andformed thereon, such that the molded base 23′ forms a reinforcingportion of the circuit board 22′. Therefore, during the manufacturingprocess, the molded base 23′ will reinforce the circuit board 22′ toprevent the deformation of the circuit board 22′, so as to enhance theimaging quality of the array imaging module.

According to the preferred embodiment of the array imaging module, themolded base 23′ forms the reinforcing portion of the circuit board 22′when the molded base 23′ is integrally formed with the circuit board22′, so as to reduce the cumulative tolerance of the array imagingmodule and to enhance the imaging quality of the array imaging module.

In addition, the photosensitive unit 21′, the circuit board 22′, and themolded base 23′ are combined to form an integrated structure, theflatness of the photosensitive unit 21′ will not be restricted by theflatness of the circuit board 22′, such that a thinner circuit board22′, such as the flexible circuit board, can be used for reducing thethickness of the array imaging module.

FIGS. 18 to 24 illustrates the array imaging module as a dual lenscamera module. As shown in FIG. 18, the array imaging module can beformed as a multiple lens camera module having multiple optical lenses10′.

FIGS. 18 to 22 illustrate the manufacturing process of the moldedphotosensitive assembly 20′ of the array imaging module. FIGS. 23 to 25illustrate the manufacturing process of the array imaging module withthe molded photosensitive assembly 20′.

Referring to FIG. 18, the two photosensitive units 21′ are coupled atthe two chip coupling areas 222′ of the circuit board 22′ respectively,wherein the chip connectors 211′ of the photosensitive units 21′ areelectrically connected to the chip coupling areas 222′ of the circuitboard 22′ via the lead wires 24′ respectively. The electronic elements26′ are electrically connected at the peripheral area 223′ of thecircuit board 22′. The electronic elements 26′ are spaced apart fromeach other. Once the array imaging module is formed, the electronicelements 26′ will not be mutual interfered with each other.

Through the connection of the lead wire 24′ and its physical properties,the chip connecting terminal 241′ of the lead wire 24′ is electricallyconnected to the chip connector 211′ of the photosensitive unit 21′ andthe circuit board connecting terminal 242′ of the lead wire 24′ iselectrically connected to the circuit connector 221′ of the circuitboard 22′. Then, each of the lead wires 24′ is bent to protrude upwardlyabove the top side of the photosensitive unit 21′. It is appreciatedthat during the manufacturing process of the array imaging module, eachof the lead wires 24′ is retained at its original state to keep the bestelectrical conductivity of the lead wire 24′ so as to enhance theimaging quality of the array imaging module.

As shown in FIG. 19, at least a portion of the non-photosensitive area213′ of the photosensitive unit 21′ is enclosed by the respectivesupporting body 251′, wherein the photosensitive area 212′ of thephotosensitive unit 21′ is aligned with the through hole 252′ of therespective supporting member 25′. Therefore, the supporting members 25′,the photosensitive units 21′, the circuit board 22′, and the lead wires24′ form a semi-product of the array imaging module. According to thepreferred embodiment, at least a portion of each of the chip innerlateral side 2131′, the chip connecting portion 2132′, and the chipouter lateral side 2133′ of the photosensitive unit 21′ is enclosed bythe respective supporting body 251′. In other words, the supportingbodies 251′ will cover the connections of the chip connecting terminals241′ of the lead wires 24′ and the chip connectors 211′ of thephotosensitive units 21′. During the molding process, the supportingbodies 251′ will prevent the molded base 23′ contacting to theconnections of the chip connecting terminals 241′ of the lead wires 24′and the chip connectors 211′ of the photosensitive units 21′, so as toprevent any disconnect at the chip connecting terminals 241′ of the leadwires 24′ and the chip connectors 211′ of the photosensitive units 21′.

Since the supporting bodies 251′ cover the connections of the chipconnecting terminals 241′ of the lead wires 24′ and the chip connectors211′ of the photosensitive units 21′, the chip connecting terminals 241′of the lead wires 24′ and the chip connectors 211′ of the photosensitiveunits 21′ can be separated by the supporting bodies 251′. During themolding process, the supporting bodies 251′ will prevent the deformationof the chip connecting terminals 241′ of the lead wires 24′ and the chipconnectors 211′ of the photosensitive units 21′, and will prevent anydisconnect at the chip connecting terminals 241′ of the lead wires 24′and the chip connectors 211′ of the photosensitive units 21′.

In addition, a portion of each of the lead wires 24′ is enclosed by therespective supporting body 251′, such that the lead wires 24′ areretained in position by the supporting bodies 251′. In other words, thelead wires 24′ will not be deformed during the molding process.Therefore, the supporting bodies 251′ can prevent each of the lead wires24′ from being deformed to contact with the neighboring lead wires 24′which may cause the short circuit, so as to ensure the quality of thearray imaging module.

In one embodiment, the supporting body 251′ is formed by adhesive tocouple at the non-photosensitive area 213′ of the respectivephotosensitive unit 21′, such that when the adhesive is solidified, thesupporting body 251′ provides a predetermined elasticity. Once thesupporting body 251′ is formed, the inner lateral side 252′ of thesupporting body 251′ forms the through hole 252′ of the supportingmember 25′, such that the photosensitive area 212′ of the photosensitiveunit 21′ is aligned with the through hole 252′ of the supporting member25′. In addition, since the supporting body 251′ can be formed byadhesive to have a predetermined adhering ability, contaminants, such asdust or residue, can be adhered onto the supporting body 251′ so as toprevent the contamination of the photosensitive area 212′ of thephotosensitive unit 21′ for enhancing the imaging quality of the arrayimaging module. For example, the supporting body 251′ is formed betweenthe electronic element 26′ and the photosensitive area 212′ of thephotosensitive units 21′, such that the contaminants, such as weldingpowders, from the welding process of the electronic element 26′ on thecircuit board 22′ will be adhered by the supporting body 251′, so as toprevent contamination of the photosensitive area 212′ of thephotosensitive unit 21′.

Preferably, the supporting body 251′ is formed by applying the adhesiveon the non-photosensitive area 213′ of the photosensitive units 21′,such that when the adhesive is solidified, the shape of the supportingbody 251′ is retained at the non-photosensitive area 213′ of thephotosensitive units 21′ to prevent the supporting body 251′ fromflowing to the photosensitive area 212′ of the photosensitive unit 21′so as to prevent contamination of the photosensitive area 212′ of thephotosensitive unit 21′. In other words, the shape of the supportingbody 251′ can be adjustably modified via the solidification of theadhesive to prevent the deformation of the supporting body 251′ duringthe solidification process, so as to ensure the supporting body 251′being retained at the non-photosensitive area 213′ of the photosensitiveunits 21′. It is appreciated that after the connection between the chipconnecting terminals 241′ of the lead wires 24′ and the chip connectors211′ of the photosensitive units 21′ and the connection between thecircuit board connecting terminals 242′ of the lead wires 24′ and thecircuit connectors 221′ of the circuit board 22′, the chip connectingterminals 241′ of the lead wires 24′ are enclosed by the supportingbodies 251′ after the solidification of the adhesive, so as to preventthe chip connecting terminals 241′ of the lead wires 24′ during thesolidification process of the adhesive.

As shown in FIG. 20A, the molding process is operated by a mold 100′ toform the molded base 23′ after the mold material is solidified. Throughthe molding process, the size of the array imaging module is reduced andthe assembling error of the array imaging module can be minimized so asto configure the array imaging module to have a compact size and toimprove the imaging quality of the array imaging module.

In particular, the mold 100′ comprises an upper mold body 101′ and alower mold body 102′, wherein at least one of the upper mold body 101′and the lower mold body 102′ is movable and operable in a controllingmanner. When the upper mold body 101′ and the lower mold body 102′ areclosed and coupled with each other, at least two mold cavities 103′ areformed therewithin. Accordingly, the molded base 23′ is formed bysolidifying the mold material which is placed in or injected into themold cavities 103′.

In one embodiment, for example, the lower mold body 102′ is stationaryand the upper mold body 101′ is movable to couple towards the lower moldbody 102′ to close mold 100′, wherein the mold 100′ is opened by movingthe upper mold body 101′ away from the lower mold body 102′. When theupper mold body 101′ is moved downwardly to couple with the lower moldbody 102′ to close the mold 100′, the mold cavities 103′ are formedtherein. In another embodiment, the upper mold body 101′ is stationaryand the lower mold body 102′ is movable with respect to the upper moldbody 101′ along guiding posts, such that when the lower mold body 102′is moved upwardly to couple with the upper mold body 101′, the mold 100′is closed and the mold cavities 103′ are formed therein, and that whenthe lower mold body 102′ is moved downwardly away from the upper moldbody 101′, the mold 100′ is opened for drafting.

When the semi-product of the array imaging module is placed in the uppermold body 101′ and/or the lower mold body 102′, the mold 100′ is closedby coupling upper mold body 101′ with the lower mold body 102′ to formthe mold cavities 103′ therein. The mold engaging surface 1011′ of theupper mold body 101′ is pressed on the top side 2501′ of the supportingbody 251′, wherein the upper mold body 101′ is supported by thesupporting body 251′ to prevent the upper mold body 101′ being directlypressed against the lead wires 24′, so as to protect the lead wires 24′from being damaged during the molding process. It is worth mentioningthat the peripheral area 223′ of the circuit board 22′ of thesemi-product is set corresponding to the mold cavity 103′.

It is worth mentioning that each of the mold cavities 103′ forms anannular shape and the two mold cavities 103′ are communicated with eachother, such that the mold material filled in the mold cavities 103′forms the molded base 23′ after it is solidified.

Preferably, due to the elasticity of the supporting body 251′, thesupporting bodies 251′ will absorb the impact from the upper mold body101′ when the mold engaging surface 1011′ of the upper mold body 101′ ispressed on the top sides 2501′ of the supporting bodies 251′, so as toprevent the impact force transmitting to the photosensitive units 21′.In other words, the supporting bodies 251′ prevents the photosensitiveunits 21′ from being damaged and to prevent the dislocation of thecircuit board 22′ due to the impact force. It is appreciated that thesupporting bodies 251′ not only absorb the impact force to prevent theimpact force transmitting to the photosensitive unit 21′ but also ensurethe photosensitive units 21′ coupled at the circuit board 22′ with itsflatness, so as to enhance the imaging quality of the array imagingmodule.

Preferably, in one embodiment, the height of each of the supportingbodies 251′ is higher than the height of the apex of the lead wires 24′as the lead wires 24′ being bent to protrude upwardly above the top sideof the photosensitive unit 21′. During the operation of the mold 100′,the mold engaging surface 1011′ of the upper mold body 101′ is pressedon the top sides 2501′ of the supporting bodies 251′. The top sides2501′ of the supporting bodies 251′ will bias against the upper moldbody 101′ to prevent the further downward movement of the upper moldbody 101′, so as to prevent the mold engaging surface 1011′ of the uppermold body 101′ from being pressed against the lead wires 24′. In otherwords, each of the supporting bodies 251′ creates a predetermined safetydistance between the mold engaging surface 1011′ of the upper mold body101′ and the lead wires 24′. In another embodiment, the height of eachof the supporting bodies 251′ is the same as the height of the leadwires 24′, wherein during the operation of the mold 100′, the moldengaging surface 1011′ of the upper mold body 101′ is merely contactedwith the lead wires 24′. However, the mold engaging surface 1011′ of theupper mold body 101′ cannot apply a substantial pressing force againstthe lead wires 24′.

In addition, due to the elasticity of the supporting body 251′, the moldengaging surface 1011′ of the upper mold body 101′ is pressed on the topsides 2501′ of the supporting bodies 251′ to slightly deform the topsides 2501′ of the supporting bodies 251′, so as to prevent any gapformed between the mold engaging surface 1011′ of the upper mold body101′ and the top sides 2501′ of the supporting bodies 251′. In otherwords, the mold engaging surface 1011′ of the upper mold body 101′ andthe top sides 2501′ of the supporting bodies 251′ are tightly engagedwith each other in a surface-to-surface engaging manner. As a result,the photosensitive areas 212′ of the photosensitive units 21′ throughthe through holes 252′ of the supporting members 25′ respectively willbe enclosed in a closed environment during the molding process.Therefore, when the mold material is introduced into the mold cavities103′, the mold material will not be entered into the closed environmentand contaminate the photosensitive area 212′ of the photosensitive unit21′. It is worth mentioning that the Shore A hardness of the supportingbody 251′ has a range between A50 and A80, and the elasticity of thesupporting body 251′ has a range between 0.1 Gpa and 1 Gpa.

In addition, during the molding process, the mold engaging surface 1011′of the upper mold body 101′ and the top sides 2501′ of the supportingbodies 251′ are tightly engaged with each other, to prevent the edgetrimming of the molded base 23′, so as to enhance the imaging quality ofthe array imaging module.

FIG. 20B illustrates an alternative mode of the manufacturing process ofthe molded photosensitive assembly 20′ according to the presentinvention, wherein the supporting body 251′ can be made of rigidmaterial. In other words, when the mold engaging surface 1011′ of theupper mold body 101′ is pressed on the top sides 2501′ of the supportingbodies 251′, the top sides 2501′ of the supporting bodies 251′ will notbe deformed, so as to enhance the electrical conductivity of the leadwires 24′ and to ensure the quality of the array imaging module and theimaging quality of the array imaging module. It is worth mentioning thatthe Shore A hardness of the supporting body 251′ is larger than A70, andthe elasticity of the supporting body 251′ is larger than 1 Fpa.

The mold 100′ further comprises an enclosing film 104′ provided at themold engaging surface 1011′ of the upper mold body 101′, wherein whenthe upper mold body 101′ and the lower mold body 102′ are coupled witheach other to close the mold 100′, the enclosing film 104′ is sandwichedbetween the mold engaging surface 1011′ of the upper mold body 101′ andthe top sides 2501′ of the supporting bodies 251′, so as to ensure thephotosensitive area 212′ of the photosensitive unit 21′ in a closedenvironment.

It is worth mentioning that when the enclosing film 104′ is sandwichedbetween the mold engaging surface 1011′ of the upper mold body 101′ andthe top sides 2501′ of the supporting bodies 251′, a gap is formedbetween the mold engaging surface 1011′ of the upper mold body 101′ andthe top sides 2501′ of the supporting bodies 251′. In addition, theenclosing film 104′ will provide a buffering effect at the mold engagingsurface 1011′ of the upper mold body 101′ to prevent the impact forcedirectly applying to the top sides 2501′ of the supporting bodies 251′,so as to prevent the impact force transmitting to the photosensitiveunits 21′, the circuit board 22′, and the lead wires 24′.

In addition, the enclosing film 104′ is removed from the mold 100′ afterthe molded base 23′ is formed during the molding process.

Referring to FIG. 21, the mold material, in liquid state, is introducedor injected into the mold 100′ to fill the mold cavities 103′ until themold cavities 103′ are fully filled with the mold material at thenon-photosensitive areas 213′ of the photosensitive units 21′ and partof the supporting bodies 251′, so as to prevent the mold materialfilling into the closed environment. In other words, the supportingbodies 251′ can block the mold material passing from thenon-photosensitive areas 213′ of the photosensitive units 21′ to theclosed environment and can block the mold material passing from the gapbetween the top sides 2501′ of the supporting bodies 251′ and the moldengaging surface 1011′ of the upper mold body 101′ to the closedenvironment.

It is worth mentioning that the mold material can be formed by fluidmaterial or solid particulate material, or a mixture of fluid materialand solid particulate material. It should not be limited to either oneof the liquid material or solid particulate material, and a mixture offluid material and solid particulate material in the present invention.When the mold material is filled into the mold cavities 103′, the moldmaterial is solidified to form the molded base 23′. In one embodiment,the mold material in liquid form is implemented as a thermoplasticmaterial, such as in a liquid state, wherein the mold material filledinto the mold cavities 103′ of the mold 100′ to form the molded base23′. It is worth mentioning that after the mold material is filled intothe mold cavities 103′ of the mold 100′, the solidification process,such as heating or cooling process, for solidifying the mold material toform the molded base 23′ should not be restricted in the presentinvention.

As shown in FIG. 22, when the mold material is filled into the moldcavities 103′, the supporting bodies 251′ will block the mold materialentering into the photosensitive areas 212′ of the photosensitive units21′, so as to form the molded base 23′ after the solidification of themold material. Once the molded base 23′ is formed, at least two opticalwindows 231′ are correspondingly formed, wherein the optical windows231′ are aligned with the photosensitive areas 212′ of thephotosensitive units 21′ and the optical lenses 10′ respectively.Therefore, a light channel is formed corresponding to the photosensitivearea 212′ of each of the photosensitive units 21′ and the respectiveoptical lens 10′ through the optical window 231′. Accordingly, themolded base 23′ is formed to have a main mold body 232′ covered at theperipheral portion 223′ of the circuit board 22′, and at least a portionof the outer lateral side 2503′ of each of the supporting bodies 251′,and the top side of each of the supporting bodies 251′. In other words,the molded base 23′ is constructed to have the main mold body 232′ andat least two optical windows 231′, wherein the light filters 40′ and thedrivers 30′ are then coupled to the top side of the molded base 23′ soas to retain the drivers 30′ corresponding to the optical lenses 10′along the photosensitive paths of the photosensitive units 21′respectively.

Through this configuration, the distance between two adjacentelectronic elements 26′ is reduced, and the mutual interference by theadjacent electronic elements 26′ can be avoided. The main mold body 232can further prevent the contamination generated from the electronicelements 26 to the photosensitive areas 212′ of the photosensitive units21′, so as to enhance the imaging quality of the array imaging module.

In addition, the electronic elements 26 are individually enclosed by themain mold body 232′ to prevent the mutual interference by the adjacentelectronic elements 26′, such that the distance between two adjacentelectronic elements 26′ is reduced. Even though the area of the circuitboard is reduced, more electronic elements 26′ can be electricallycoupled at the circuit board 22′ with a limited installing area toenhance the imaging quality of the array imaging module. In addition,the electronic elements 26 are individually enclosed by the main moldbody 232′. Even though the distance between the photosensitive unit 21′and the electronic elements 26′ is reduced, the main mold body 232′ canprevent the mutual interference between the photosensitive units 21′ andthe electronic elements 26′. Therefore, the photosensitive areas 212′ ofthe photosensitive units 21′ can be enlarged within the limited area ofthe circuit board 22′ to enhance the imaging quality of the arrayimaging module.
